` To all-whom it may concern Beit known that ave, Lonnouzv :CAMPBELLand..FRANK G. .CaMBELn citizens of the United Statesyresiding at,IYashingtom in the` District: of Columbia, have invented certainnew`and useful Improvements in Detachable Pulleys .for'Automobiles ofwhich'l the following is a. specification.

yThis invention relates yto detachable. pul-l leys for automobilesjandhas-for its object to provide cert-ain improvements in `this class of.vehicles comprising improved means vto renv der it possible. to use thepower plant of the automobile to drive other machines than theautomobile. l i f f I Further objects. land advantages ofthe -inventionwill beset forth -in thel detailed description whichv now follows. n.

In the accompanying drawings,"A l

detachable pulley adapted to be lsecured to the driving wheel of.` anautomobile,

. Fig. 2.. isa detail'view of al bolt used in Y securing, said pulley inposition, f l mannereof engagement of. saidbolt with the spokes of thewheel,

Fig. 3 is ya detail view illustrating-the Fig. 4 is a rear face view ofthe pulley. Like numerals designate corresponding parts in all of thevfigures of the drawing.

Referring to the drawing, the numeral 5.

Adesignates the' hub of the driving wheel of the automobile; 6, thespokes; 7, the telly;

8, the usual clencherN-rim'; 9j, theitireg. 10, the brake drum, andI 11,the hub cap.'` The parts so far described are all of the usual and wellknown construction In carrying out the invention,l a cup-like pulley. 12is provided having a peripheral 'A 40v wheel. 20 designates ratchet lugsextending from the rear face ofthe pulley and lying in advance ofcertain of the spokes, these l v lugs being covered preferably withshort sections of rubber hose 21 to prevent marring of the spokes. It'is these-ratchet lugs that Figure 1 is'va 'view partly insection of aowner yof said automobile for many purl poses such for instance asdriving a circular saw, running a feed cutter, pumping water andmanyother purposes, if-means are provided for transmittingfy power .fromsaid power plane to said machines. This pulley provides such means-` Itmaybe attached in a few minutes-to the driving wheel of the automobileand by lifting said wheel from the ground and starting it to rotate inthe .usual Awayepower may be transmitted by' a belt v(not shown) yfromthe pulley 12 to any other machine. l l l From the foregoingdescription', it will be seen thatM simple"andeiicient means are hereinprovided for, accomplishing the objects of the invention, but whiletheelements Kshown and described are well-adapted to serve the purposesfor which they`r are intendedpit is to be-understood that the vention isnot limited to the precise construction set forth, but includes withinits-purview such changes as may be llmade'vvithin thescope of theappended claims. Having described our invention what claim is:v 1"".1'.'In' a device of thecharacter described the combination with awheelhaving a projecting hub, a detachable pulley comprising a body portionand a central conical portion which converges from a diameter greater95' than the diameter of said hub to a diameter less than the diameterof said'h'ub, means for y. drawing said pulley toward saidl wheel andrigid driving members attached to said pulley and engagingsaid wheel.

2. In a detachable pulley for automobiles,

'the combination with a pulley body portion of a central conicalcentering'member, a wheel having spokes and meansfor drawing saidlpulley toward the spokes of said wheel.

V3. In a detachable pulley for automobiles,

the combination Witha'pulley body portion of a central conicalcentering' member, a'

wheel vhaving spokes, means for drawm said pulley toward thev spokes'ofsaid whee and rig id `members prgjecting vfrom said 4. In al detachablepulley for automobiles,

' 5 the combination with a wheel having spokes,

' lof a pulley body' portion, a -centrally located cone 'for centeringsaid body portion withref lation to the hub'of the wheel to whichv saidpulley is applied, and means f or drawing said Vbody portion toward thespokes-df said wheel.

@5. In a detachable pulley for automobiles, the combination with a wheelhaving spokes, Acfa pulley comprising a bodyportion havmg sald bodyportion `with relation to the hub of the wheel to vwhichfsaid pulley isapplied, means-for drawing said body,l portion toward the spokes of saidwheel and rigid driving members projecting inwardly fromv said .bodyportion between the spokes of the Wheel to receive the thrust thereof.

6. In adetachable pulley for automobiles,

the combination .with a wheel having spokes,l of a body portion having aconical Vcentral portion, bolts the heads of which engage the spokes ofthe wheel, said bolts -passing through said body portion, membersthreaded jupon saidA bolts for forcing said body portionv toward thespokesv of the wheel and f 'rigid members projecting rearwardly fromsaid body portion and extending between the spokes of the wheel toreceive the thrust of said spokes. v

.35 7. In ladetach'able pulleyjjor automobiles,

the combination Awith :a'whe'el of a pulley body portion having' a'central conical centering ortion, T-bolts. the heads of whichvengageehind .thespokes of the wheel to which the 40 pulley is applied and the`Shanks of which pas through said body portion, members/ I threaded uponsaid Shanks upon the outer me ofsaid' bodyportion and rigid driv (ngmembers projectingfrom the rear side a hollow conical. centerforcente'ring `greater than the diameter of said hub to i of said bodyportion and extending. between the spokes of thewheel. f 8. a detachablepulley for automobiles, the combination with awheel of a ulleybody-portion having a central'conica centering portion, T-bolts theheads of' .which a engage behind the spokes 0f the wheel to which thepulley is applied and the Shanks. of 'which pass through said bodyportion, members threaded upon said Shanks lupon the .outer'side of saidbody portion and rigid driving members projecting from the rear sideofsaid body portionand extending between the spokes fof the wheeL-ther'ebeing elongated slgs formed in said bodyiportion through whichzsaidShanks pass. eo 9. In a detachable pulley/for automobiles thecombination with va pulley'body portion of a central conical centeringmember. I0. In a. device of the character described the, combinationwith a wheel having a hub and spokes, of a detachable' pulley, conlpris-4 ing means for centering said pulley upon the hubof the wheel-and means for drawing said pulley toward the spokes of the wheel.

l1.` In 'a device of the character described, the combination with awheel having a 'prjecting .hub of a detachable pulley comprising a bodyportion and a central conical portion which converges from adiameterdiameter less than the diameter offsaid hub and which is of such sizewith relation to the hub that it will vcenteritself upon' the hub beforeits body portion 4.contacts withfthe spokes of the Wheel and means fordrawing said pulley toward said wheel.

Intestimony whereof we aiix our` signatures in presence of twowitnesses.
